I built a Flite Line Demon in 1973.
Quite a story. I had just returned from SEA and was living in an apratment with zero building faciliites. I had won the kit at contest a few years earlier.
My new flyng buddies told me the airplane was obsolete, undersize, and didn't have a chance against a Motivator or a Nemisis. I said, "maybe so, but it't the only kit I've got right now."
At the contest, the Tangerine in Jacksonville, I won the first round and lost the second. The "Motivator guy" won both rounds but used up all his toys.
I loaned him the Demon and he went on to take second place and wreck the model.
Despite freak success, lesson-learned. I never built a plane that small again.
In retrospect, it was a short, sweet modeling experience. A lot of planes don't take a second place in a much longer life.
